Second guessing my relationship

I’ve been with my boyfriend for 2 years, but I have been knowing him for 7 years. I am in love with him but unfortunately I think it’s time for me to walk away.

I’m noticing some changes or either they were there all along and I were blinded to them. So I feel like he is in agreement to his family whether they’re right or wrong and I’m ALWAYS wrong. I could say the exact thing someone of his family said and he’ll disagree with me but agree with them. Also, I noticed he makes excuses for his family and justifies their actions but if it was me I need to figure out how to change whatever it is.

I also noticed that the way his siblings raise their children is not the way I’d raise ours. And before I have kids with him I need to figure out what I need to do.

I’m afraid that He’s not ready to move on from his family to start one of his own.
